Re: Toshiba 49U5863DB Vestel 17MB130S, blank screen, no image, sound ok.
Hi.
if I can, I would advise you to raise all the smd as indicated in the photos, obviously paying close attention.
carefully check, raised at least on one side, the indicated capacitors, in particular the indicated transiator, it is certainly short-circuited.
in case it was the transistor I will give you the solution in private messages.
finally the 10mf 50v capacity is the right one...Leave a comment:

Re: Sony Bravia KDL-60W855B
Hi.
As you explain, I don't think it's a ripple or bad filtering problem.
as your colleagues have advised you, you could via usb, but if as you say, now it does not start perfectly, I do not think the update procedure starts.
In that case the last resort would be to, save the dump fw, rewrite it by extracting the keys-Leave a comment:

Re: Sharp Aquos LC-60LE600U no power period
Hi.
if real this measure
Pin 24 STB = 0.58 V.
no it's normal, you should have a voltage between 5v and 3.3V.
as you say that Pin 14 PS_ON = 2.07V.
hypothesis?
isn't it that you have a faulty stand by circuit?Leave a comment:
